Persistent pain can be frustrating, particularly when you do not know what is causing it. A painful shoulder, knee, ankle or tendon problem may affect your everyday activities and make exercise increasingly difficult.
Musculoskeletal ultrasound, commonly known as MSK ultrasound, is an imaging technique that can be used to assess certain muscles, tendons, joints and other soft tissues.
When clinically appropriate, MSK ultrasound can provide additional information alongside a physical assessment, helping clinicians develop a clearer understanding of certain musculoskeletal problems.
What Is MSK Ultrasound?
MSK ultrasound uses high-frequency sound waves to produce real-time images of structures within the body.
It can be used to assess various soft tissues, including selected tendons, muscles, ligaments and joints.
One of its useful features is the ability to perform dynamic assessment. This means certain structures can be observed while the body moves, depending on the area being examined and the clinical question.
MSK ultrasound is non-invasive and does not use ionising radiation.
Why Might MSK Ultrasound Be Recommended?
Pain does not always reveal exactly which structure is responsible for symptoms.
For example, discomfort around a joint may be associated with different muscles, tendons, soft tissues or joint structures.
If symptoms persist or the clinical picture requires further investigation, MSK ultrasound may provide useful additional information.
It can be particularly relevant when assessing certain soft-tissue problems.
However, imaging is most useful when considered alongside symptoms, medical history and physical examination.
What Can MSK Ultrasound Examine?
The areas that can potentially be assessed include different regions of the body.
Shoulder
Shoulder pain can involve several structures working together around the joint.
Ultrasound can provide images of selected tendons and soft tissues around the shoulder when clinically appropriate.
Elbow and Forearm
Repetitive activities, exercise and sports can place significant demands on the elbow and forearm.
Ultrasound may help assess certain soft-tissue structures when symptoms require further investigation.
Hip and Groin
Hip and groin pain can have multiple possible causes.
A detailed clinical assessment helps determine whether MSK ultrasound may be useful and which structures should be assessed.
Knee
Knee symptoms may develop following an injury or gradually over time.
Depending on the symptoms, ultrasound can be used to assess selected soft tissues around the knee.
Ankle and Foot
The ankle and foot contain multiple muscles, tendons, joints and other structures involved in movement and weight-bearing.
Ultrasound may be appropriate for investigating certain soft-tissue problems in this area.
MSK Ultrasound and Physiotherapy
MSK ultrasound can complement physiotherapy when additional information about a musculoskeletal problem is required.
Physiotherapy assessment considers more than an image.
A clinician may evaluate your:
- Symptoms
- Movement
- Strength
- Joint mobility
- Activity levels
- Previous injuries
- Functional limitations
If ultrasound is appropriate, its findings can then be considered alongside this information.
This helps create a more complete clinical picture.
Dynamic Ultrasound Assessment
One feature that makes ultrasound particularly useful for certain musculoskeletal assessments is dynamic imaging.
Structures can sometimes be observed while a person moves the affected area.
For example, the clinician may ask you to move a joint or perform a specific movement while observing the relevant structures.
This can provide information that may not be visible during a completely static assessment.
The exact approach depends on the body area and the reason for the scan.
MSK Ultrasound for Sports Injuries
Sports injuries can affect muscles, tendons and other soft tissues.
When symptoms persist or the diagnosis requires clarification, MSK ultrasound may sometimes be considered.
This can be particularly useful for active individuals because understanding the condition can help inform rehabilitation and return-to-sport planning.
However, the scan itself is only one part of the process.
A successful return to sport may also require appropriate strengthening, mobility work, movement training and progressive exposure to sporting demands.
Ultrasound and Injection Therapy
MSK ultrasound can also be relevant when certain injection treatments are being considered.
Ultrasound guidance can allow the clinician to visualise relevant structures during selected procedures.
This may help with accurate placement when an ultrasound-guided procedure is clinically appropriate.
However, not every person with pain requires an injection.
The decision should be based on the individual’s symptoms, diagnosis, medical history and clinical assessment.
A suitable clinician can explain the available options and whether a particular treatment may be appropriate.
What Happens During an MSK Ultrasound?
The appointment usually begins with a discussion about your symptoms and the reason for the examination.
You may be asked about:
- When the symptoms started
- Where the pain is located
- Previous injuries
- Activities that affect your symptoms
- Previous treatment
- Your current level of activity
The clinician will then assess the relevant area.
A small amount of ultrasound gel is applied to the skin, and the ultrasound probe is moved over the area being examined.
Depending on the body part, you may be asked to change position or perform certain movements.
The process is generally straightforward and non-invasive.
Is MSK Ultrasound Painful?
The ultrasound scan itself is generally non-invasive.
The probe moves across the skin using ultrasound gel.
However, if the area being examined is already painful or sensitive, pressure from the probe may reproduce some discomfort.
It is important to communicate with your clinician during the assessment if you experience significant discomfort.
What Happens After an MSK Ultrasound?
The next step depends on the clinical findings and your symptoms.
Your clinician may discuss the results with you and explain what they mean in relation to your condition.
Depending on the circumstances, recommendations may include:
- Physiotherapy
- Rehabilitation exercises
- Activity modification
- Further assessment
- Injection therapy where appropriate
- Referral for additional medical investigation
The findings should be interpreted in the context of your symptoms rather than viewed in isolation.
Why Imaging Does Not Always Tell the Whole Story
An important point about any form of medical imaging is that findings on a scan do not necessarily explain every symptom.
Some changes can occur without causing pain, while symptoms may sometimes exist even when imaging does not show an obvious abnormality.
This is why clinical assessment remains important.
MSK ultrasound should be considered a tool that can provide additional information rather than a complete replacement for history and physical examination.
MSK Ultrasound and Long-Term Recovery
Understanding your condition can help you make more informed decisions about treatment and rehabilitation.
If a musculoskeletal problem is affecting your movement or exercise, a combination of appropriate assessment, treatment and progressive rehabilitation may help you work towards improved function.
For active individuals, this can also involve gradually rebuilding strength and tolerance to activity.
The appropriate recovery plan depends on the individual and the nature of the condition.
When Should You Consider an MSK Assessment?
You may benefit from professional assessment if you have:
- Persistent joint pain
- Ongoing tendon symptoms
- Pain following a sports injury
- Reduced movement
- Recurrent soft-tissue problems
- Pain that is limiting exercise
- Symptoms that have not improved as expected
A clinician can determine whether further investigation, including MSK ultrasound, is appropriate.
A Clearer Approach to Musculoskeletal Problems
Musculoskeletal pain can have many different causes, and understanding the problem is an important first step.
MSK ultrasound can provide detailed, real-time information about selected soft tissues and may complement a wider clinical assessment.
When combined with appropriate physiotherapy and rehabilitation, the information gained from assessment and imaging can help guide the next stage of care.
If you are experiencing persistent musculoskeletal pain or an injury, arrange a professional assessment to discuss your symptoms and determine whether MSK ultrasound or another form of investigation may be appropriate.
